What's Happening

  • Peak Butterfly Season

    Great Spangled Fritillary

    While butterflies can be found on the refuge in all the warm seasons right up until a killing frost, late June through mid July is usually the most active time of the year. Over the next few weeks, the greatest variety of species can be found. Many of the small grass skippers will be active along with several swallowtail species, sulphurs, hairstreaks, fritillaries and much more. The best place to look for butterflies is in the open fields with full sunlight and a diversity of flowers for nectaring. Milkweed is one of the most desired nectar sources and it is plentiful along many of the refuge trails. The north loop of the Dagmar Dale Trail, The Liberty Loop Trail and Winding Waters Trail can all be excellent places to observe these beautiful creatures. If you are out looking for butterflies, please do not attempt to capture them with nets as this can damage their scales. Close focusing binoculars are the best way to observe them. In mid July the 18th annual butterfly count will be conducted on the refuge. Refuge staff and volunteers will spend an exhaustive day in the field to count all the species and numbers of individuals that can be identified. The data from this count and all other counts in North America is compiled in a data base maintained by the North American Butterfly Association (NABA). Results of the count will be posted later in the month.
